Recommended Posts

Have one in my bay. Confirmed the one way clutch blew up, and sets codes for solenoid E(overdrive) stuck on. Can someone explain to me why it starts out in 4th gear when this happens? Confirmed 4th gear start by watching ratio pid. When the wrench light comes on, only then will it start in 1st, also confirmed by ratio pid.

I have a lot to learn in the area of transmissions but I will take a stab....

Looking at the shift chart if solenoid E is stuck on that will be 4th then if the PCM turns off the TCC that is manual 1.

 Hopefully I didn't miss too badly :cover:

For now I will take your word on it. The WSM states that a damaged OWC will cause a launch in 4th. Not sure how that is because the Low reverse clutch should be on providing 1st gear at launch. And the code for E solenoid stuck on takes me straight to diagnosis of the OWC in symptom charts.
